U.S.A. studies and claims the air pollution can cause people's blood pressure to rise
Www.xinhuanet.com Los Angeles Cable of September 15 (reporter's plateau) A latest research in U.S.A. reveals, will make people's blood pressure rise to suck the air polluted in two hours continuously, the serious one will also initiate cardiovascular vessel disease.
The researchers from U.S.A. Michigan university say, though for healthy people, exposed to leading to the fact while polluting the air blood pressure is raised temporarily there is not too great danger, but to cardiovascular problematic person, blood pressure that the air pollution causes may initiate having a heart attack or apoplexy while rising.
Researchers have been here for a period newly>Say, they have tested the blood pressure change of 83 volunteers on the magazine, these people are arranged in a laboratory, it is about equal that degree of pollution and city of indoor air near the degree of pollution in the area of road. Researchers sucked them before and after polluting the air the change of blood vessel and blood pressure has been measured.
Result find after not sucking, polluting the air in the two hour, relaxation of participant pigeonhole (low to pigeonhole) Rise to some extent, and its blood vessel presents the damaged sign. Disappear attacks direct of once pollutant,blood pressure will thereupon decline,it is be long to last 24 hour blood vessel's damage to cause. Researchers analyze that find, it is the small particulate matter in the air to initiate the main factor that blood pressure raises and makes the blood vessel damage.
Study director Robert and Brook and remind and say, if predict that reveals the air pollution index is relatively high, the person who suffers from heart disease, diabetes or lung disease should control and reduce the outdoor sports.
